Think of it this way, when you are riding a 21 speed bike and you are on the 21th speed, how long does it take you to down shift to 3rd gear. Yes, I agree with you that the software can be more agressive, but thats what the sport mode is for, it keep the tranny in a lower gear and has a different throttle map, much like your sprint booster.

I think the hardware is fine. If it isn't, no amount of sport mode can help. The normal mode programming just sucks, and that is the root cause for all of us that is having these lags.

I just hope BMW realizes that the issue is still not resolved and will release software updates for our 2011 builds. Seems they have solved the issues in the 2013 models (from previous posts in this thread).

I agree, to a certain extent.

Update: Just picked up my car from service yesterday and it drives much better it terms of lag and acceleration smoothness and I’m quite happy with how it turned out.

Here are the issues that bother me though, As said before, from the time I got the car until now, I thought the acceleration and shifting characteristics were normal. It turns out during service that the Mass Airflow Sensor had permanently failed. It has been replaced and while there picking up the car I was told by my SA that the car was “reprogrammed” as well. But I could find no reference to reprogramming on the service invoice.

Either way; the acceleration lag is gone, the car drives like the loaner did, and I’m left with even more questions. Since I got the car (5 miles on it), it has always driven the same, in other words I can’t remember a time before this service visit where I noticed a change in its drivability.

Is it possible that the sensor was bad from the very beginning… in a brand new car?
Is it possible that the car was actually reprogrammed during service? (it did take a few days to get it back)
Is it possible that the Airflow sensor was indeed responsible for the lag?
Is it possible that this is my imagination?

I have attached the service invoice so that all may see exactly what (they told me) was done.

Well, I got my baby back after having the "global update" performed and I must say there is big difference in how she runs. The hesitation is gone (responds like the JB3 does) when in non-sport mode and she seems to have more spring in her step. I'm going to run her JB3 free for a few days just to get the "real" feel of her running bareback again. I was depressed last week before the global update as she was a bit sluggish and hesitated at times (especially when compared to having the JB3 on her). It will be interstiing to see/feel the difference when I slip the JB3 back on her. But I must say guys, the update does make her feel better. I know some have complained that right after the update the hesitation, etc. was gone but after time it has reappeared. I won't go too long before I put the JB3 back on so I doubt I'll experience the return of the hesitation (if indeed it were to return).

I've attached the work order for reference to the SIB.

Any chance you might do a dyno before and after so we can see what it really adds?

Are you going to update to the JB4 Stage 1...likely a harness update? I can tell you that the JB4 I have added is fantastic from every perspective. Thanks for the tip.

Yes, I'm afraid that there are lots of people think that their cars are fine. Well, I guess if there's no comparison, it's hard to know what we're missing.

Regarding your questions, I'm puzzled too. It doesn't make much sense that you are able to drive with a bad airflow sensor since day 1. I'd imagine the engine would either run rough or that your gas mileage would be bad. But again, I'm sure they do not fix things that ain't broke either.

Well, keep driving it for a few weeks and see if the lag returns.

Before the service visit;
The car did idle roughly, the gas mileage was never better than 18.7, and the breaks squealed relentlessly since day one, at that time I was told, "its just because they're new"

Anyone that got a software update for Accleration problem, noticed that default start mode is now COMFORT, before my update it was ECO, any body else notice this after this fix ? BMW Service also did AUTO STOP to last position, so I dont know.

I just want to say THANKS for that information. I told my dealer about this information, and they were able to update the software on my car. It drives completely different now. I also had to wait 2 days, as far as I can tell so far it was worth the wait.

Wow. I'm truly amazed at how accepting folks appear to be about this issue, while others have sued BMW outright. In my 46 years of life - new / used cars alike -I've never had one that hesitated / delayed like the one car I spent the most money on, is way more high end than those before it, and was the one - among all - in which I rightfully had such high expectations. The tip in issue that's apparently plagued BMW's for years now, is a safety issue, period. Yes, BMW drivers get used to it, adjust, switch to sport mode, etc... but that is not why sport mode was created, nor is it a solution for an automatic car. If it was their intent, you can be sure they would not be on top of fixes for the past 3-4+ years or more. For those that may still follow this thread, or come back to it at some point... I just took my 2011 528i (garage kept and barely 25k miles) into the shop because the AC was no longer producing cold air. They found a leak in the evaporator. While there, I asked - as I have in past visits and visit specifically to address the tip in issue - that they revisit the integration software to ensure I have the most current 'fix'. Upon updating my vehicle with F010-14-03-503, my car drove the worst it ever has, on the ride home from the dealership, and the most shocking was that the same hesitation and delay is now occurring in SPORT MODE AS WELL! I called them immediately, enraged and requesting a call from the service manager who waited more than 24 hours to return my call. He only called me back after I left a vm for my service coordinator, indicating the issue seems to be slightly better than it was on my drive home. So, guess what the service manager says when he calls me? >>> The car is learning how I drive, and adjusting accordingly. How clever. Has anyone heard of this? Is this what they say when you a customer says they've noticed slight improvement, or is this really possible? Regardless, I will now devote my time and attention to successful suits filed. Unlike - perhaps - most BMW owners, I don't have $50-$60k to lay down on a car that runs worse than a $30k car. BMW needs to address this with those affected, in a way that says we screwed up and we know it, and we're doing something about besides a software patch! When I asked why they haven't done so, the service manager said because not all BMW owners were affected... not all make and models, etc. Well, I'm certain they know or could easily ascertain through vehicle / purchase records, and that's also part of the point / process of a recall. Simply astounded that BMW purchasers are not requesting, expecting and demanding more of this company. Accountability... standing behind product issues is important. Please contact me if you're aware of any legal approaches surrounding this issue, as that is my next step. My dealer ignored me, then acted like they didn't know what I was talking about, then acted like I was crazy and all the while they knew EXACTLY what i was saying was accurate.

Wow! What a rant! Save yourself the trouble of a lawsuit. Sell the car you don't like. Bite the bullet on the depreciation and buy yourself another car. Life's too short for a long and painful lawsuit that is going to cost you more time, money and energy than it is worth.

I've seen the 'tip in' problem in many other cars with auto transmissions. It seems worse in some more than others. I've had the same issue in a ZF Auto in my 1999 Land Rover (problem would temporarily go away when you reset the adaptive drive or used "S" mode - sound familiar?), it was a problem in my wife's Toyota, it's noticeable to some extent in most rentals that I've been in. I've always chalked it up to the adaptive transmissions that have been around for over a decade. Engines with less power made the problem less noticeable. However, it has been one of the many reasons I prefer to row my own gears.

Quintus - Wasn't asking for an opinion on what I should do, and am entitled to rant. Consider offering valuable information to a post on a forum, that exists precisely for that reason, verses inflicting 'your' opinion of what another finds upsetting and/or offering unsolicited advice.

ImolaREdm - Thanks for sharing useful information. Had no idea this issue exists in vehicles from other auto makers. Before buying my BMW, I purchased 3 used Land Rovers through the years, and - fortunately - never experienced anything remotely similar. They had small oil leaks and - at times - other minor issues, but actual drive performance was always great (which, thereagain, I would expect from any high end car manufacturer).

Same here. I didn't know cars can have such serious throttle delays until I bought my 2011 F10. My wife's X1 and my parents Mercedes (S and C) did does not exhibit anything close to this. I've done the software upgrade and it is somewhat better now. But the other day, a serious delay happened out of the blue again. I tried to blip the throttle to change lanes and the car did not respond. Then I floored the pedal. Nope. No response at all. I was mad and I stomped the pedal quickly two more times. Nothing again. Finally, the 3rd time, the engine responded.

It is unfortunate that this will not be fixed in our early build F10s until some one gets injured with proper documented material that links the accident with the throttle delay.

I guess what Quintus said is true. It might be best just to sell it and get an LCI (I assume they have fixed the issue in the LCIs)
